AC Power Adjust wheels

I know an older guy 60 miles away that has a WD 45. He wants the wheel spacing changed and can't find anyone close willing to help him. I'm thinking about telling him I'll do it for him. It's been over 40 years since I changed wheel spacing on a WD, help refresh my memory on the process. If I remember correctly, AC had a special tool to loosen and tighten the locks, a 12 or 16 bar with square socket on each end and a hole to put a bar thru it. Turn it to loosen, start tractor, hold your foot on the opposite brake and spin the wheel forward or backwards to move wheel where you want it and tighten the lock back up. What am I forgetting?? Do the locks get frozen over the years and are difficult to impossible to move?? If he doesn't have the special tool, is there a socket that will fit the lock? Seems like it was a square head on the lock. He is talking about trying to find regular rims that will fit the WD and replacing the power adjust wheels. I'd help him, just trying to find out what all is involved. Thanks, Chris
 
I'm going from memory too. My experience is with Massey 65.

I still have the original tool. It seems like it might be a 3/4 inch square ??? There should be a couple saddle clamps for location unless they got lost. An 8 point socket should work unless they are rusted tight.

You might get lucky and find things aren't all rusted up.
 
a socket will fit. Try loosing the one on top first because it has no weight on it to make it turn hard. They will turn hard. We moved them wheels a lot when we cultivated corn.
 
I was wrong, it is a 1/2 inch square on my Massey.

Pictures show the saddle clamps Massey used and the OEM wrench.

If you can find one a 25/32 six point socket works perfect. Mine is a impact and I just use a long breaker bar. The stop block can be problematic, soak it with your penetrating oil of choice.

If you cannot get the adjusters to turn, loosen the two bolts on each piece that holds the adjusters then jack up the wheel and spin them around.Use plenty of oil.
 
I just adjusted the wheels on our WD45 last year. They haven't been adjusted for at least 40-50 years.

Use plenty of WD-40 beforehand. Let it soak for awhile if the bolts are rusted. PB-blaster tends to really "stink" up things so be careful using too much. That smells sticks around for awhile from my experience.

I used a big breaker bar and socket and each clamp broke loose with some elbow grease. I didn't need to jack the tractor up. I think I went in reverse to extend the wheels out? I just can't remember. If you aren't sure the tractor brakes are working, you can always block the front of the tractor from going anywhere too.
 
did a pair on a WD45 that had been rattle can restored, needed to take the wheels off and it was still a bear to move them. That was probably 17 years ago they have not moved since. Probably would need to take the wheels off again to move them.
 
If the cams will turn it is an easy job. If not you need to take the center wheel out, two bolts on each cam bracket, and work on the cams/brackets one at a time and they can be a witch. If the tractor has been under cover it may well be easy, if out in the weather for years, maybe a project. There is a snap ring on the other end of where the wrench goes on the cam shaft. Taking apart, cleaning, greasing will make them nice but if they are loose you probably don't need to do that.
